Kilopascals to Psi Converter
How to convert kilopascals to psi
psi = kilopascals ÷ 6.89475729
To convert kilopascals to psi, divide the number of kilopascals by 6.89475729.
1 kPa = 0.145037738 psi
Examples
- Standard sea-level atmospheric pressure: 101.325 kPa ÷ 6.89475729 = 14.6959488 psi
- 220 kPa ÷ 6.89475729 = 31.9083023 psi
Good to know
One psi is about 6.895 kPa, and 100 kPa is about 14.5 psi. Tire placards in many countries show both units.
Psi means pounds-force per square inch (lbf/in²). Gauge readings (psig) are measured relative to atmospheric pressure, absolute readings (psia) relative to a vacuum; the conversion factor is the same for both.

Unit definitions
- Kilopascal (kPa)
- A kilopascal is 1000 pascals. It is the common SI unit for tire pressures, weather reports and engineering in metric countries.
- Psi
- Psi is one pound-force per square inch, about 6894.757 pascals. It is the everyday pressure unit in the United States, used for tires, compressors and plumbing.
